Here's one question that I have about Star Wars. In Episode IV, R2 and C3PO land on Tatooine and are eventually purchased by Owen Lars. Owen and the bots do not recognize each other. The bots do not recognize the place.
Now, fast forward (or rewind, if you please. Damn prequels) to Episode II. CP3O is working at the moisture farm when Anakin shows up with R2D2.
This could be explained if the robots had their memory wiped, but how the hell would Owen completely forget about 2 robots he had already met, one of which he had previously owned?
Sorry, this has been bugging me for a while.... Had to get it off my chest.
